Magnitude 3.4 earthquake hits gas field region of north Netherlands
Decades of gas extraction have led to dozens of minor tremors every year in Groningen, damaging thousands of homes, sparking unrest among locals and prompting authorities to impose caps on activity.
Earthquake is among the most severe to ever hit the region but there were no immediate reports of casualties or damage.
The Groningen field is run by NAM, a 50-50 joint venture between Royal Dutch Shell and Exxon Mobil. ■
